To @ZZ whom t 'may conce/rn.'

Be it known that l, Josemi CnossLnY, a citizen ci the United States,residing at rlfrenton, in the county of Mercer and State of NewJersey,have invented certain new and useful Improvements y'in DrivingMechanism, of which the following is a specilication.

This invention relates to driving` mechanism tor use in connection withwashing machines, and is adaptable particularly to the washing machine:illustrated and described in my copondingl application Vfor LettersPatent, Seria-l Number 429,478, tiled Decem.- ber 9, 1920, of which ,thepresent application is a division. n

The primary or Igeneral object of' the invention isto provide gea-ringof an improved nature for developing the energy ot a motor or otherpower source into rotary movement and transmitting such movement to theclothes containing cylinder of the washing machine,

A further object of the invention is to provide mechanism for thepurpose stated which operates automatically at predetermined cyof theparts is at alltimes assured, with the possibility ot breakage, wear orderangement of any of the parts being remote.

A still further object of the invention includes the improved manually icontrolled clutch mechanism, which in a facile manner, enables theoperator ot the machine to instantly and accurately control themovements and operation of the latter.

`With these objects in view, together'. with others which will appear asthe description proceeds, the invention consists in the novelconstruction, combination and arrangement ot parts, all vas will bedescribed more fully hereinafter, illustrated in the drawings, andparticularly pointed `out in the claims.

its the improved gearing'disclosed herein lis primarily for use inconnection with washing machines it will be described as adapted to thatuse, but it l'will be understood that such association is not to beconsidered. as a limitation ot the invention to siich use, as theinvention is applicable to a varietyot machines or mechanisms wherealternating rotary driving movements'are required. i f

i wall of the wash tub is indicated generally at and to' this wall andupon the interior ot the tub a motor 3() issecure'd. "This motor isenclosed by a water tight casing, and the shaft 31 oi the motor, whichitend's trans\'iersely into the tub,fis provided with a suitable packinggland to vpreclude, the entrance oi? water to the interior of the motorcase.` lhe motor, as will be understood, will be energized by beingwired with a sui" Jblc source et electrical energ f, and the operaton otthe `motor is controlled by the push button switch indicated at 35arranged in the hase ot' the motor.

rllhe power gearingior the washing inachine isconlined within a casingdisposed within the tub and secured to one end wall thereoin adjacent tothe. motor 30 and below theplane of the latter. The' outer end of thisvcasing terminates in an annulus 37 which has arranged therein a. wormvgear 38. Thisfworm gear is engaged by'a worm-39 drivenby the sha't 3loi the motor. ln theA present instance, the worm is disposed beneath acup 40 to receive a suitable lubricant,

taken substanby a housing 59, the inner end of-which is of lequaldiameter with and Yengages 'theH edges of annulus 37.v Screws or boltsmay be employed for securing this housing to the casing, and it will beunderstood that a water tightconnection between the casing and housingmust be established. The housing has arranged centrally therein a shaft60, the said shaft being alined with the central opening 61 in the wormgear 3S. The shaft is hollow and receives a slidable clutch carrying rod62 extending throughout the length of the said shaft. rlhe inner endofthis rod carries a clutch member 63 adapted to engage with the clutchface Get carried by worm gear 38, and when the rod is retracted thisclutch member is withdrawn from the said clutch face and is conlinedwithin the head 65 at the extreme inner end of shaft 60. As shownparticularly in Figs. 1 and 2 of the drawing, the gear 38 has a centralopening to receive the head 55. The rear face of the gear 38 has securedthereto a plate, as indicated in Fig. l, and this plate is provided withthe clutch face Gil to receive the clutch member 63 carried by the rod62. When the rod is moved to its limit in one direction, the clutchmember 63k will protrude from head 65 and engage with 'the clutch face64- of the plate, whereby a positive drive connection is establishedbetween gear 38 and the head 65, while retraction of the clutch member623 vfrom face 64 breaks this power connection and the said member isthen wholly housed by the head 65. rllhe outer end of the rod 62 isprovided with a grooved head 66 which is engaged a pin carried by arm G7connected to operatii'ig rod 68. ll his rod is mounted in suitablebearings in housing 59 and protrudes at one end to the exterior of thehousing. The protruding end ot the rod is equipped with a handle ($9 toenable the same to be readily operated.

The hollow shaft 60 is provided inwardly from its ends with a worm 70engaged by worm wheel 71 carried by the worin shaft 7:2 disposedtransversely of the housing. This worm shaft has also secured thereon acani wheel 73., havingcam surfaces ill-"5 at its -able bearings withinthe housing and dis-r posed transversely thereof, and has a recess Z9 inone face thereof to receive a lug S0 projecting laterally from the upperedge of the rocker plate Sil. T his rocker plate is supported at itslower end by a bushing S2 extending forwardly from the same and littingwithin bearing S3 in the forward face of the housing. The bushing 82receives and rotatably supports the rotatable cylinder operating shaftSe, the forward end of which is squared as at 85 to engage with thecylinder socket, while the inner end of the said shaft has a spur gear86 allixedtherem to. The rocker plate 81 has trunnions 8T, 88 and 89projecting therefrom, and upon which are rotatable pinions 90, 91 and92; the trunnions 8?*89 being so disposed that the pinions w-92 carriedthere-by are at all times in mesh with the gear 86, while trunnion Sl'sso disposed that the pinion 91 carried thereby is in mesh with ypinion92. The pinions 90-91 are adapted to be brought alternately into meshwith gear 93 secured to shaft 60. rll`his movement of the gears iscaused by operation of the rocker plate 81 through instrumentality ofcam wheel 73, as will be understood. lt is apparent that Iby thearrangement of pinions Q1- 92, the

ried by the worm gear 38. The mechanism within the housing at oncebecomes active, and the hollow shaft 60 at once begins to ro tate, andthe cylinder operating shaft will rotate in one direction or the other,depending upon which of the gears 99 or 91 is engaged with the gear 93.'As the hollow shaft rGO rota-tes. the worm wheel 70 is turned, as

is cam wheel 73. As the cam wheel continues to turn, one of the canifaces thereof will move out of engagement with its cooperating roller"Z6, while the cam face upon the opposite side of the wheel will contactwith its cooperating roller, and through the instrumentality of the pin77 supporting said roller, will force the gear shifting bar to move;said movement causing roclrerplate 8l to correspondingly ymove. Thismovenient of the rocker plate disengages from gear 93 the pinion whichhas heretofore been in mesh therewith, and causes the said gearifi-tacos it will be understood that two or more of such faces may beprovided if desired, and it will be understood further that the periodicnumber of rotations in opposite directions of shaft Set may becontrolled by increasing or decreasing'the length` of the said cam faceson the opposing faces of wheel 73.

The clothes containing cylinder or basket is indicated diagrammaticallyat 95, and it will be understood that this cylinder may be of anypreferred type or style and may be rotatably mounted in any desiredmanner in the tub.

From the foregoing, it is obviousl that I have provided mechanism fullycapable of carrying forth the objects mentioned above for which it isparticularly adapted, and although the above is a description of theinvent-ion in its` preferred embodiment, it will be understood that theinvention is lnot to be limited to the precise structure or use setforth, as variations in adaptability and detailed arrangement mayberesorted to if desired without departing from the invention as definedby the claims.
